Abstract: Aspects of the present disclosure provide techniques for configuring a search space for sidelink communications between one or more sensors/actuators (SAs) and programmable logic controller (PLC) in internet of things (IoT) applications in order to minimize the number of subchannels that a receiver (e.g., PLC or SA) may need to blind decode. More particularly, the search space is configurable based on a hashing function that is based in part on a portion of the resources (e.g., PLC resources) that have been allocated or reserved for sidelink communication within the PLC subnetwork (or PLC group) from the sidelink resource pool available to a plurality of PLCs in a network. By limiting the search space to a subset of resources that are specific to the PLC subnetwork or group, the need for the SA or PLC to perform blind decoding of sidelink control information (SCI) may be further reduced.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a vehicle-to-everything (V2X) capable wireless device configured to perform sidelink cellular communications. The wireless device performs sidelink communications using a two-stage sidelink control information (SCI) protocol including Stage 1 SCI messaging carried on a physical sidelink control channel (PSCCH), and Stage 2 SCI messaging carried on a physical sidelink shared channel (PSSCH). The SCI messaging may be encoded using polar codes. Channel interleaving is utilized on the SCI to interleave the SCI between two or more layers of a MIMO transmission system. Scrambling for Stage 2 SCI messaging is performed based on the result of a cyclic redundancy check (CRC) performed on Stage 1 SCI messaging. Collisions between sidelink HARQ feedback to be transmitted to a base station and other transmissions are avoided based on a priority analysis of the sidelink HARQ feedback.

Abstract: A V2X event-message dictionary and a binning function are received from a cloud server. Sensor data is compared to events specified in the V2X event-message dictionary to identify a best-fit event for the sensor data. A number of bins and a bin number for the event are computed using the binning function. A V2X message is transmitted including the number of bins and the bin number, thereby avoiding including the sensor data in the V2X message.
